I love this idea!! Infact, I'm all in love with the person behind this very idea!
It is not a pre-planned itinerary, it was a out-of-the-blue suggestion to have a day-trip, somewhere out of city center, and that's lead us to Cameron Highlands.
Travelling on early monday morning before the rest of the world gets to rush towards their respective route, to their respective place of work, turn out to be a better choice for travelling at ease. We decided to used the epic-Tapah route to Cameron. It is a narrow-winding road, but we made it through to the peak without any car-sickness. The weather was awesome, the temperature was indicating at 21 deg celcius with a bit of drizzles from time to time.
